CHU-RN.

SPECIFICATION forming part of Letters Patent No. 516,970, dated March20, 1894.

' Application filed April 7, 1893. Serial No. 469,422. (No model.)

To wZZ whom it may concern.-

Be it known that 1, WILLIAM D. HAMMOND, a citizen of the United States,residing at Businessburg, in the county of Belmont and State of Ohio,have invented a new and useful Improvement in Ohurns, of which thefollowing is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction ofchurns, to increase their efficiency and to enable butter to be rapidlyproduced, and to cause the butter to collect in a roll to facilitate itsseparation and removal.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective view of a churn embodying theinvention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is atransverse sectional view. Fig. 4 is a detail perspective view of thedasher cylinder, the detachable peripheral plate being removed. Fig. 5is a similar view of the detachable peripheral plate.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings. V

1 designates a churn body having a curved bottom 2 and provided at itscorners with legs 3 and 4. The legs 4: are provided at their lower endswith sockets 5 and have secured within them upturned ends 6 of ahorizontal spindle 7, which has mounted on it wheels or rollers 8. Therollers 8 are separated and retained at the ends of the churn body by asleeve 9, which is arranged on the shaft and disposed between therollers 8. By having the two legs 3, which rest directly upon a floor orsupporting surface, and the other leg 4, which are provided withrollers, the churn body is supported in a steady mannerduring operation,and maybe readily moved from one place to another on the rollers 8. I

Within the churn body is mounted on j ournals 10 and 11 a revolvingdasher cylinder 12, which is composed of end disks 13 and a series ofsubstantially tangentially disposed the butter collects in the inside ofthe dasher I cylinder, but some collects in large lumps outside, thelumps of butter being too large to readily pass through the peripheralopenings between the plates. This outside butter may be readily pushedthrough the spaces between the plates into the dasher cylinder, afterwhich a few rotations of the cylinder'will cause the loose butter tocollect in a roll. The

butter is removed from the cylinder through an opening formed by theremoval of a detachable peripheral plate 16, which is provided at theinner ends of its securing flanges with notches 17 for engagingprojections 18 on the inner faces of the end disks 13. The removableperipheral plate is retained in position by a spring 19 arranged on theouter face of one of the disks 13 and having one end secured to thesame, and its other end 20 bent at an angle and arranged in aperforation of the disk and engaging a perforation 21 of the adjacentflange of the removable peripheral plate.

On the ends of the dasher cylinder are fastened bearing plates 22 and23; the bearing plate 22 has acentral concavity for receiving thejournal 10 5 and the other bearing plate 23 has a central rectangularopening, which receives a squared end 24 of the journal 11. The journal10 has a threaded shank 25 to enable it to be adj usted; and the outerend of the shank terminates in a thumb piece; and a jam nut 26 isarranged on the threaded shank to limit the inward movement of thejournal. The journal 11 is provided adjacent to its squared end with anannular flange to form a tight joint to prevent the escape of the liquidcontents of the body through the opening for the journal; and the latterhas a threaded stem 28 on which is secured a crank handle 29. Theannular flange 27 is held in close contact with the inner face of theadjacent end of the body by a fiat spring 30, secured to the body andarranged on the exterior of the same and disposed above thejournal l1and having its lower end extended outward and provided with a notch andengaging the opening end of the bar of the crank handle to force thejournal outward. The ends of the body are provided with projectinghandles; and the cover 31 has a central perforation over which isarranged a vertical vent tube 32 formed integral with a securing late33.

It will be seen that the churn is simple and comparatively inexpensivein construction, that it is eflicient in operation and effects a rapidproduction of butter, and that the butter may be collected in a roll andreadily removed. The dasher cylinder is removable from the body by meansof the journals, and after the operation of churning has been completedit is taken from the body, and the butter within it may be readilyremoved by means of the detachable peripheral plate. provided at itsupper edges with projecting angle flanges 3% arranged at the corners to'receive the corners of the cover, which is recessed to form shoulders35 to prevent displacement. These angle flanges 34 are formed by thelegs of the .body 1; and the legs consist of angle irons and projectabove the upper edges of the body and are arranged in the recesses ofthe cover.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

The cylinder is of great ad vantage in holding the butter while thebuttermilk is drawn off, and it enables the butter to be readily and Thebody is,

conveniently Washed with cold water or treated with salt water.

What I claim is 1. In a churn, the combination of a body and a rotatingbutter collecting dasher mounted within the body and comprising ends anda series of substantially tangentially disposed peripheral platesconnecting the ends and forming an interior chamber, one of the platesbeing removable to afford access to the chamber, substantially as andfor the purpose described.

2. In a churn, the combination of a body, and a rotating dashercylinder, composed of circular ends and peripheral plates provided attheir ends with securing flanges, one of the plates being detachable andprovided in its flanges with notches, projections arranged on the innerfaces of the ends and engaging the notches, and a spring having one endbent at an angle and extending through the adjacent end piece andengaging the detachable plate, substantially as described.

3. In a churn, the combination of a body,

the journals mounted in the body and having threaded shanks, one of thejournals being loosely mounted and having its inner end squared andprovided with a flange, and the other journal engaging a threadedopening of the body a rotating dasher cylinder mounted on the journaland having a square opening at one end to receive the squared journal, acrank handle attached to the loosely mounted journal, and a springsecured at one end to the body and having its other end engaging thecrank handle, substantially as described. In testimony that I claim theforegoing as my own I have hereto affixed my signature in the presenceof two witnesses.
